Providing physical host hardware state information to virtual machines deployed on the physical host

Abstract

A device may receive, from a virtual machine deployed on the device, a request to register for an event associated with a hardware component of the device, and may create a path to a script associated with providing information about the event when the event occurs. The device may provide the script to an event plugin associated with the event and the hardware component, and may register the event plugin with a kernel associated with the device. The device may receive, the kernel, information indicating occurrence of the event associated with the hardware component, and may cause, via the event plugin, execution of the script based on the occurrence of the event associated with the hardware component. The device may provide, based on execution of the script, a notification to the virtual machine, where the notification may indicate the occurrence of the event associated with the hardware component.
